## JWT Lens Description
JWT Lens is a fast, private JSON Web Token decoder and verifier for developers — a Safari extension that works entirely on your device.

Tap the toolbar icon, paste a token (or grab the text you&#039;ve selected on the page), and instantly see:

• Pretty-printed, color-coded Header and Payload
• Human-readable timestamps — exp, iat and nbf shown in your local time with relative phrasing (&quot;expires in 59 minutes&quot;)
• An at-a-glance expiry badge: valid, expired, or not yet valid
• Plain-English descriptions of standard claims (iss, sub, aud, and more)

Need to check a signature? JWT Lens verifies HS256/384/512, RS256/384/512, PS256/384/512 and ES256/384/512 using a secret or PEM public key you provide — all computed locally with the system&#039;s WebCrypto, never sent anywhere.

Privacy by design:
• No network requests — ever
• No analytics, no tracking, no accounts
• Nothing is stored: tokens and keys live only in the popup while you use it

Whether you&#039;re debugging OAuth / OIDC flows, inspecting a bearer token, or learning how JWTs work, JWT Lens keeps it quick, clear, and completely on-device.

Universal app: works in Safari on macOS, iOS and iPadOS.
